Description

   Protective masks with inserted nose pads   

The present invention relates to a mask, and more particularly to a protective mask with an inserted nose pad.

In recent years, the rapid development of industry and cities has resulted in serious air pollution caused by exhaust gases emitted from various factories, coal-fired power plants and a large number of automobiles and locomotives, leading to the deterioration of air quality. Dust in the environment is fine suspended particulates (PM2 .5) Invasion of the human body through the respiratory tract causes various diseases such as bronchitis, asthma and cardiovascular diseases, which seriously endangers human health. At the same time, the World Health Organization (WHO) confirmed in 2013 that air pollution is the main human carcinogen. Seven of the top ten causes of cancer death in Taiwan are closely related to air pollution. In addition, in recent years, various bacterial viruses and influenza in the living environment have continuously invaded humans, such as severe acute respiratory syndrome (SARS), bird flu, and swine flu (H1N1). Is the killer of human health, showing that masks are increasingly important to human health.

At present, various protective masks in the world have reached tens of billions of pieces, about 80% of which are flat non-woven masks. Common flat masks on the market and even some N95 series dust-proof masks are easy to carry and cheap, but the adhesion is generally poor. . According to the Taiwan standard CNS14774 and 14755 protective mask (N95 / FFP2) D2 tightness test method, the mask must be worn to achieve a closeness of 100 (100% ÷ 100 closeness = 1% leak rate), according to Taiwan labor safety and health Tested by 100 people from the Institute, the average tightness of two commercially available N95 masks was 13.9 and 21.8, while the average of ordinary flat masks was only 3.10, which means that the average air leakage rate was 33%, so the effect of dust haze (PM2.5) Great discount. In order to maintain a certain degree of adhesion, at present, most common masks have been equipped with plastic nose lines such as plastic strips or plastic-covered iron or aluminum strips on the upper edge to improve the degree of adhesion to prevent the gap between the nose and the face. . However, due to the shape, size, and height of the nose of the mask, the most prone to leakage is also the most difficult to prevent. When you press the nose line with your hand, it will be shaped slightly, and you will still have a slight face after wearing it for a few minutes. Large gaps are created by muscle activity, especially masks rely on elastic earbands or straps on both sides to support them, making it easy for pollutants and viruses and bacteria in the air to "take advantage of them" for many years has been a fatal shortcoming of masks .

Long-term inhalation of dirty air that has not been filtered by a mask can cause many cancers and diseases, such as chronic diseases such as hypertension and diabetes, and even cause complications and death. When entering or leaving a medical institution or public place, it is easy to infect each other and increase the chance of infection. . Also, because most masks are worn against the nose and mouth, the ventilation is concentrated on the mouth and nose area, which increases the breathing resistance and forces more air to leak from the gap. Therefore, the main cause of the general leakage rate is about 40%. The higher the danger, the higher. This is a big defect in non-woven flat masks that has been difficult to improve significantly for several decades.

Furthermore, the heat exhaled from the body of the mask wearer will also rise upward from the bridge of the nose, fogging the glasses, affecting the sight, and even driving safety. In addition, there are masks on the market with nasal bridge foam. Because the foam has a certain thickness and is placed between the mask and the bridge of the nose, the foam and the sides are still prone to pores, making the mask unable to effectively fit the face shape and greatly reducing the airtightness of the nose. effect.

In view of this, one of the objectives of the present invention is to provide a protective mask with an inserted nose pad. By forming a convex portion on the upper edge of the mask body, the inner layer can be closely adhered along the nose bridge and the sacrum curve, and can be effectively filled. The gap between the mask and the nose greatly increases the tightness of the nose.

Another object of the present invention is to provide a protective mask with an inserted nose pad. The mask body is formed with horizontal and longitudinal folds, and when expanded into a body shape, the mouth and nose space and ventilation area can be enlarged to make breathing smooth. Speak naturally and reduce breathing resistance.

A third object of the present invention is to provide a protective mask with an insertable nose pad. By forming a convex part on the upper edge of the mask body, the convex part can fill the gap between the bridge of the nose and the sacrum, so as to prevent the exhaled mist from passing through the mask. The body (10) directly rises upward to prevent fogging of the glasses.
